  • revert to original "type_trac" management:
    • 4 characters keyword (lmdz, Inca, repr, co2i, into, aeNP, coag
    • no longer a list of component with "|" separator
    • the parsed (with "|" separator) version "types_trac" is no longer used
    • the sole routine using a list of component is readTracFiles
  • fix for INCA and CO2Aer modes: setGeneration is now a function, index corrections for had/vadv.

4! Purpose: Initial states and boundary conditions files creation:
5!     * start.nc    for dynamics    (using etat0dyn     routine)
6!     * startphy.nc for physics     (using etat0phys    routine)
7!     * limit.nc    for forced runs (using limit_netcdf routine)
8!-------------------------------------------------------------------------------
9! Notes:
10!     * extrap=.T. (default) for data extrapolation, like for the SSTs when file
11!                   does contain ocean points only.
12!     * "masque" can be:
13!       - read from file "o2a.nc"          (for coupled runs).
14!       - read from file "startphy0.nc"    (from a previous run).
15!       - created in etat0phys or etat0dyn (for forced  runs).
16!     It is then passed to limit_netcdf to ensure consistancy.
